Simulation mode of UCC28C43

Han Peng

Other Parts Discussed in Thread: UCC28C43, TINA-TI

I would like to use UCC28C43 controller in a shunt regulator simulation in LTspice. However, once I applied the pspice model in LTspice and ran the simulation, the error message is as follows.

Anyone knows how to modify the spice model to be compatible in LTspice? Or can anyone send me a LTspice version of model?

Thanks

Hi Han,

We do not provide model for LTSpice. As an alternate, we provide TINA-TI models which can be found in the product folder. TINA-TI is a free simulator provided by TI. If that does not work for you, please refer to the following post regarding getting access to unencrypted models.

Thanks,

Hi! Thanks for your reply. I think I will need the unencrypted model for UCC28C43. Could you guide me how to get it? Any link for downloading?

Thank you!

Hi Han,

The instructions were provided in the previous link. Here is the excerpt:

3. Many models on www.ti.com continue to be encrypted. If you do need these in unencrypted format, please contact your TI Field Applications Engineer or submit a request through www.ti.com/support and they should be able to help you with this request. Note that this may need a valid NDA with TI.

Thanks,
